CLIFFORD L. HART, OF NEW BRITAIN, CONNECTICUT,

FLOOR AND CEILING PLATE.

Specification of Letters Patent.

Patented se t. 5, 1916.

Application filed August 10, 1915. Serial No. 44,801.

To all whom it may concern Be it known that I, CLIFFORD L. HART, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Floor and Ceiling Plates, of which the following is a specification.

My invention relates to improvements in floor and ceiling plates, and the object of my improvement is simplicity and economy in construction and convenience and efficiency in use.

In the accompanying drawing :Figure 1 is a plan view of my improved floor and ceiling plate. Fig. 2 is an edge view of the same. Fig. 3 is a rear view of the same. Fig. 4 is a view on an enlarged scale with the parts in the open position. Fig. 5 is a plan view of the blank for one of the latch members. Fig. 6 is a plan view of the blank for one of the body members. Fig. 7 is a sectional view on the line as m of Fig. 4.

My improved floor and ceiling plate comprises two mating shell-like body members 10 that meet along opposed edges suitably to form an annular plate, having a flat top and a turned peripheral edge, inclosing a hole to fit the pipe, and which are connected at one end by a hinge connection and at the other end by a latch and may be opened out to receive the pipe and closed around the pipe, and locked in the closed position. Each of the members 10 has mounted in a recess in the member 10 a spring 13, held in place by lugs 14, said springs being adapted to engage a pipe when clamped by the members 10. As shown the said springs 13 are generally V-shaped, the side arms being sprung under the lugs 14, and having the middle portion 15 bent approximately circular to form a head for holding the spring in place. The free ends 16 of the springs 13 project inwardly into the space inclosed by the body members 10, suitably to engage the pipe. The said hinge connection comprises a pair of overlapping hinge lugs 11, connected by a rivet 18 or other suitable form of pivotal connection.

The latch 12 comprises latch plates 19 supporting cotiperating latch lugs 20 and 30, suitable for being passed by one another and to be sprung into engagement one behind the other, to efiect a locking of the members. The latch lug 20 is a spring member, made of sheet material, and has a nose or catch 31 that engages with the other latch lug 30, which last named lug 30 serves as a keeper.

The hinge lugs 11 are supported by hinge plates 21 in generally the same manner as the latch lugs 20 and 30 are supported by the latch plates 19.

The hinge plates 21 and the latch plates 19 serve as auxiliary plates. said plates is generally rectangular, and of such length as to fit across on the inside of the body member 10, as a lining therefor, being positioned adjacent the end, suitably to properly position the particular arm for the hinge or latch member, and has at the inner end a turned up edge that is cut away at the middle portion to form a pair of stop lugs 22, separated by a recess 23. At the outer ends of the auxiliary plates 21 and 19 the material is curved, suitably to fit snugly against the turned edge 24 of the body member 10. The'said outer ends of the auxiliary plates 21 and 19 are each cut away at the middle portion to form a recess 25 at the said middle portion, separated by a pair of stop lugs 26 at the corners.

The body members 10 are each provided with inner wings or ears 27 integral with the inner edge, and with outer wings or ears 28, integral with the outer edge 24, and suitably positioned to be bent over and to engage one with the recess 23 at the inner edge of the portion 21 and the other with the recess 25 on the outer edge thereof, the base portions of the said ears fitting in the said recesses, and the body portions thereof lying over against the inner faces of the plates 21 and 19.

The ears 27 and 28, positioned as described, and by cooperation with the stop lugs 22 and 26, serve to hold the hinge members and latch members in their proper positions.

I claim as my invention 1. A floor and ceiling plate comprising a pair of mating body members, the said body members being each of approximately semicircular formation and having the ends opposed to form an annular plate, auxiliary plates fitting across the inner faces of the said body members, adjacent the ends thereof, interlocking lugs on the said body members and auxiliary plates servingto hold the said plates in position, and hinge lugs supported by the auxiliary plates adjacent one pair of the opposed ends of the said body Each of themembers and latch lugs supported by the auxiliary plates adjacent the other pair of opposed ends.

2. In a floor and ceiling plate, a body 5 member of semi-annular form, and having a shell-like form in cross-section, an auxiliary plate comprising a body portion and an arm for engaging a connection on the other semi-annular member of the ceilingg 10 plate, the said body portion fitting across ends, and the said body member having lugs on the outer and inner edges that are engaged with the said recesses.
